Lucky for all of us who love children's literature, "The ABC of It: Why Children's Books Matter" exhibit at the Stephen A. Schwarzman Building at the 42nd Street Library has been extended. Don't miss this chance to learn more about the importance of children's books: what they teach, what they reveal, and what they record, providing everyone with their own personal sense of time and place in the history of unforgettable books.
